SPECIFICATION formingpart of Letters Patent No. 669,699, dated March 12,1901.

Application filed August 14, 1900. berial No. 26,810. (No model.)

To (Jail? whom it may concern:

Be it known that I, DON JACKSON, a citizen of the United States,residing at Pleasantgrove, county of Sutter, State of California, haveinvented an Improvement in Hame' Hooks; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to a device and attachment for the hames of harnesswhereby con nection can be readily made with the traces or chains of thedraft appliances.

The invention consists of'a twopart hook, one of which has one end bentto engage the staple or fastening by which it is connected with the hameand the other end has a slot 'with an opening at one side by which theconnecting-link of the chain is introduced. The other leaf is pivoted tothe first one and turnable about the pivot-pin and has acorrespondingly-shapedslot with an opening at one side which allows itto interlock with the first-named leaf, and the two leaves are so bentthat the interlocking portions cross each other upon the opposite sidefrom the pivoted portion, thus forming a solid lock and brace whenclosed.

My invention also comprises details of construction which will be morefully explained by reference to the accompanying drawings, in whichFigure 1 is a view of the hooks being opened out. Fig. 2 shows a rearview of the same being closed.

The object of this invention is to provide a convenient, strong, andeasily-manipulated attachment for hames which when closed presents noprojecting points or angles which would be liable to catch or becomeentangled with other portions of the harness.

In the drawings, A represents the hame, having the stout link 2, bywhich the connection of the draft -,chains with the hame is made.

3 is one of the plates of the connecting device, termed hame-hook, andthis plate has one end coiled around, so as to make an elongated hook 4,which can be easily engaged with or disengaged from the link 2. Thispart of the hook has made near the opposite end an elongated slot 5,extending lengthwise of the plate, and at one side of this slot is aninclined open channel 6, through which the chain-link of the trace maybeintrodnced or removed. The other plate 7is pivoted to the first-namedplate, as shown at 8, and has made in it a slot 9, which is similar inshape to the slot 5 of the first-named plate, and it has through theside which is adjacent to the first plate a slot 10, similar to the slot6 and so made that the two slots 5 and 9 coincide when the plates areclosed by turning the plate 7 about the pivot-pin 8. The opening of theplate 7 allows the two plates to be separated sufficiently for a link tobe introduced between them, after which by closing the plates togetherthe link will be confined in the longitudinal slots 5 and 9. In order toso look these plates when closed that they will act as a single hook andto prevent any side strains from pulling them apart transversely, theseplates are ofiset or bent, as shown at 11, to a degree equal to thethickness of the plates, so that two sides of the plates are contiguouswhere they are pivoted, and the closing of the plates brings the twoopposite sides in contact at the point where the slots are made throughthem, or, in other words, the plates cross each other about intermediateof their length, so that they are firmly interlocked and are preventedfrom being pulled apart by any transverse strain which may occur.

The walls of the open slots 6 and 10 are beveled or inclined, as shown.This bevel may be either single, as shown in Fig. 1, or double, as shownin Fig. 2, and when the plate 7 is turned to one side, so as to stand atapproximately right angles with the plate 3, the two slots 6 and 10 willbe opened and separated, so that the chain-link 12 can be introducedinto the slot and the longitudinal channel 5. The plate 7 being thenclosed to interlock with the plate 3, the slotted portion 10 of thisplate moving about the fulcrum-pin 8 follows the line of the slot 6, andone edge of the slot passes upon one side of the plate 3 and the otheredge upon the other side, so that when closed the two plates lietogether and the link of the chain would be confined in the singlelongitudinal slot which is formed by thus closing the plates together,and one edge of each of the inclined slots 6 and 10 lies upon one sideof the plate 3 and the other edge upon the opposite side, as

plainly shown in the drawings. This produces a smooth link without anyprojecting angles or points to catch upon any portion of the harness,and no transverse strain will be able to separate the plates, as mightbe the case if'one was pivoted entirely upon one side of the other.

By forming the connection with the hame integral with one of the platesthe strain is removed from the pivot pin of the two plates and the draftcomes directly upon the plate itself, so that even if a pivot-pin bebroken off the connection would remain intact.

Having-th us described my invention, What I claim as new, and desire tosecure by Letters Patent, is

A hame-hook formed of two flat plates, one end of one of which is bentinto a scroll to engage the haine-staple, and the other end formed witha longitudinal slot, a diagonal 20 slot opening from this through oneside of the plate, a second plate correspondingly slotted having a pivotconnection between the ends of the first plate about which it isturnable,

said plates having their central portions bent 25 posite faces arecontiguous upon the other 30 side of the slots.

In witness whereof I have hereunto set my hand.

DON' JACKSON.
